Math rock!

I learned about a new subgenre of music at dinner the other night: math rock. Math rock? At a concert, does the band play for a few minutes and then people start yelling out answers?

“73,901.42?”
“No dude, it’s 812,839,327…that was a factorial chord, not a cosine chord!”
“Hey, that guy’s using a calculator! Poseur!”

Or is less competitive? “We’re gonna slow it down for a bit and play 1/pi to the 427th decimal point and follow that up with the Fibonacci Sequence.”
